GE IS200TTURH1CFD (IS230TNTRH1C) Terminal Turbine Board

Configured for high-speed sensor interfacing and synchronization trip routing in Mark VIe turbine control networks, the GE IS200TTURH1CFD (IS200TTURH1CFD Terminal Turbine Board) provides direct physical/electrical execution. The hardware serves as a dedicated terminal module utilized to execute speed monitoring, synchronization checking, and trip solenoid deployment across gas or steam turbine subsystems.

Hardware Specifications

GE Industrial Control and Deterministic Networks

• I/O Density Scaling and Core System Redundancy: The terminal turbine board operates seamlessly across both simplex and TMR architectures. In a TMR layout, the physical traces partition and replicate the incoming speed and voltage inputs, routing three identical hardware paths straight to independent R, S, and T processing cores to preserve system voting logic without requiring separate external signal splitters.
• Deterministic Synchronization and Relay Control: The onboard K25, K25P, and K25A relays handle critical automatic generator synchronization functions. The trace path calculates phase angle differences and voltage matching at the board level, triggering these interlock relays in real time to match the deterministic closing window of the primary network circuit breakers.

Frequently Asked Questions

Q: What specific functions do the onboard K25, K25P, and K25A relays serve?

A: These three relays form the hardware interlock matrix for the generator synchronization loop. They work in tandem with the primary logic to verify voltage, frequency, and phase alignment across the breaker contacts, closing only when the main grid parameters exactly match turbine generation states.

Q: How does the IS200TTURH1CFD interface with the TRPG, TRPS, and TRPA boards?

A: The TTUR terminal board acts as the main signal collection point, which connects directly to the TRPG (Primary Trip), TRPS (Safety Trip), or TRPA (Emergency Trip) boards via dedicated high-density cable assemblies. This inter-board link transmits speed-trip data and emergency manual command inputs straight into the master solenoid trip circuits.
